If you felt this quake (or if you were near the epicenter),
please share your experience and submit a short "I felt it" report! Other users would love to hear about it!
Also
if you did NOT feel the quake although you were in the area, please
report it! Your contribution is valuable also to earthquake science and earthquake hazard analysis and mitigation efforts. You can use your device location or the map to indicate where you were during the earthquake. Thank you!
Data for the same earthquake reported by different agencies
Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.

Aftershocks
More info
Based on its magnitude, the fault that was active during the quake ruptured along a surface of approx. 398 km
2 (=154 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 35 km (21 mi).
Aftershocks typically occur during the weeks and months following the quake at or near the same fault, at distances of up to approx. two times the length of the rupture zone.
The often broadly linear arrangement of aftershock epicenters encompasses the rupture zone of the main shock (check on the
map below to verify).
